'There’s more than meets the eye’: analysing verbal protocols, gazes and sketches on external mathematical representations (2006)

San Diego, Jonathan, Aczel, James, Hodgson, Barbara, Scanlon, Eileen

When learners are asked to verbalise their thoughts about multiple mathematical representations, some researchers are left to analyse utterances based on video records of activity which may have...

Linking multiple representations in exploring iterations: does change in technology change students’ conjectures? (2004)

San Diego, Jonathan, Aczel, James, Hodgson, Barbara

This study investigates changes in conjectures of four typical students when they are using different kinds of technologies, particularly in relation to their preferences for representations and the...

The effects of technology on making conjectures: linking multiple representations in learning iterations (2004)

San Diego, Jonathan, Aczel, James, Hodgson, Barbara

Numerous studies have suggested that different technologies have different effects on students’ learning of mathematics, particularly in facilitating students’ graphing skills and preferences for...
